locked Is there a Daily Summary mode for htis group?

Philip Karras <ke3fl@...>
 

Either I never received an email with all the commands for this group or I deleted it/never saved it.

If there is one please send it again.

If not I want to know how to change from individual email mode to daily summary mode. 

If that's not possible how do I stop my membership?

Tnx es 73 de KE3FL,

Re: Qrpometer calibration

Just for the sake of QRPoMeter builders, I have changed the calibration procedure in the past year, so that may be the source of confusion.  And the 4SQRP kits are different from the NM0S kits.

It is normal for the VSWR reading to be something besides zero with no RF applied.  But, the Power reading should be zero.  Check to see that the diodes are inserted in the correct orientation, and that they measure about 0.6v in the forward direction, using the diode checker in your multimeter.

Karen, did you move the decimal set solder short on the back of the meter?

Re: Qrpometer calibration

Thanks all,

i tried the calibration given by Glenn, but can’t get anywhere near 1.0, more on the order of 10-13. 

My kit actually has 3 test points. The 5v for 33 was fine. But the second step is to read the v at TP2 while applying 2 - 10 watts RF, derive the measured power, and then adjust the LCD to display that power. There is nothing in the instructions about TP3. Still not right, and response is not linear. 

I also note that when on, and no RF applied, the display has 0.65 for power and ~ 12 for VSWR. 

This is my first encounter with SMTs, and my next step will be re-flowing those.

You're right Dan. I'll add that to the manual as Appendix N and Ron will post that update as soon as he can.

Great additional info, Jim, Thanks. This stuff should be in the manual.

The inside dims of the HL box bottom: 7.30 x 4.875 x 2.10

The cover is .875 deep.

The Main circuit board : 7.25 x 4.82

Corner cut outs approx .400

All dims in inches.

Did not know that anyone was making a list, but you can add my name to it.  Had to take a short vacation from the build due to the weather and the fact that my bench is outside in the TX room   But our weather is back to normal and I get back to the bench tomorrow in the 80 degree heat.

Re: Qrpometer calibration

My QRPometer doesn't seem to have a TP2, at least it isn't mentioned in the calibration instruction: 
Step 8 – Calibration There is one test point on the board, above the TX connector. This is labeled TP-1. Insert a fresh 9v battery into the battery clips, and flip the bottom switch up into the ON position. With a digital voltmeter, measure the voltage between this test point and ground. You may use one of the hardware mounting holes in the corners of the board as a ground point. Adjust the trim pot R33 until this voltage reads 5.00v. 

 Locate a QRP RF power source of 0.5W to 5W power level. Connect this to the TX connector, J1. Flip both switches into the up positions, so that the meter is ON and measuring VSWR. Apply 0.5W to 5W of RF power to the TX connector, and adjust the calibration pot on the back of the LCD meter until the display reads “1.00”. It is IMPORTANT to unkey the transmitter before turning off the QRPometer! The QRPometer is now calibrated!

Hi,

I recently completed this kit
adjustment of TP-1 to 5v is fine. But calculation of power from TP-2v gives 9.5w with KX3 set to 5w. Doesn’t seem right. I adjusted the display anyway, and it fluctuates between 8.5 and 9.5w. 

Any suggestions appreciated.

Ge Karen 
The Qrp o meters have a history of needing a lot of heat on the load resistors.
Try cranking up the heat to high, then reflow them and let em soak.

It’s worth a try.

Might try a different QRP transmitter of known power level to verify the readings.

OT: For Sale QCX-Mini Verson 1 - 40 meters

Jim Sheldon
 

If anyone is looking for a nice little single band QRP rig, I have a QCX-Mini (version 1 but with the self destruct repair modifications installed and everything is working great) for 40 meters.

I finally received my Version 2 and have it on the air so I no longer need the other one. Original cost for the kit was $97 and I'm asking 90 for this one US only. I'll pay the shipping (Priority Mail).

Output power is 5+ watts and it's in cosmetically great condition.

Only the radio in the picture is included, the key and speaker are not.

PayPal is the only way I can accept payment.

First "I'll take it" gets right of first refusal - please reply off list to w0eb (at) cox dot net or via private reply to this message.

Thanks,
Jim - W0EB. 4SQRP #44
